A reusable yarn tube includes a hollow tube having a substantially cylindrical wall and an outer surface adapted to carry a yarn on the tube surface. The tube includes a starting groove in the outer surface near one end of the tube and an opposite, yarn-unwinding end. A pre-formed sleeve having a smooth surface is form-fitted about a portion of the outer surface of the tube and an end of the tube. In this manner, the sleeve provides a smooth surface for the yarn to be wound onto and unwound from the tube. Preferably, the sleeve is formed about the yarn-unwinding end of the tube and across the thickness of the cylindrical wall without contacting the inside surface of the tube. Such a reusable yarn tube is useful for preventing yarn snags on defects in and about the ends of the tube.
